Form 8915-F does show as being available on the Form Availability List. However there are some software updates being implement that have resulted in a delay. Please check back after 3/15/2024, update your software if you are in the desktop version of the software, and try to proceed with your return.
Once a form is finalized by the IRS, it has to be coded into the special language the software uses and has to be thoroughly tested for calculations and e-filing acceptability. The IRS then has to approve it for e-file. It always takes a little longer for a form to become available for e-file in a software program. The dates are subject to change due to all that needs to be done.
